<a name="GtkStackSwitcher.description"></a><h2>Description</h2>
<p>The GtkStackSwitcher widget acts as a controller for a
<a class="link" href="GtkStack.html" title="GtkStack"><span class="type">GtkStack</span></a>; it shows a row of buttons to switch between
the various pages of the associated stack widget.</p>
<p>All the content for the buttons comes from the child properties
of the <a class="link" href="GtkStack.html" title="GtkStack"><span class="type">GtkStack</span></a>; the button visibility in a <a class="link" href="GtkStackSwitcher.html" title="GtkStackSwitcher"><span class="type">GtkStackSwitcher</span></a>
widget is controlled by the visibility of the child in the
<a class="link" href="GtkStack.html" title="GtkStack"><span class="type">GtkStack</span></a>.</p>
<p>It is possible to associate multiple <a class="link" href="GtkStackSwitcher.html" title="GtkStackSwitcher"><span class="type">GtkStackSwitcher</span></a> widgets
with the same <a class="link" href="GtkStack.html" title="GtkStack"><span class="type">GtkStack</span></a> widget.</p>
<p>The GtkStackSwitcher widget was added in 3.10.</p>
<div class="refsect2">
<a name="id-1.3.7.8.9.6"></a><h3>CSS nodes</h3>
<p>GtkStackSwitcher has a single CSS node named stackswitcher and
style class .stack-switcher.</p>
<p>When circumstances require it, GtkStackSwitcher adds the
.needs-attention style class to the widgets representing the
stack pages.</p>
